If anyone does not believe that Holy Mary is the Mother of God, he is severed from the Godhead. If anyone should assert that He passed through the Virgin as through a channel, and was not at once divinely and humanly formed in her (divinely, because without the intervention of a man; humanly, because in accordance with the laws of gestation), he is in like manner godless.
Gregory of NazianzusHe took our flesh and our flesh became God, since it is united with God and forms a single entity with him. For the higher perfection dominated, resulting in my becoming God as fully as he became man.
Gregory of NazianzusDo you conceive of your Lord as less because? He shows that humiliation is the best road to exaltation (cf. Mt. 23:12); because He humbles Himself for the sake of the soul that is bent down to the ground, that He may even exalt within Himself that which is bent double under a weight of sin?... If so, you must blame the physician for stooping over suffering and putting up with evil smells in order to give health to the sick?
Gregory of NazianzusCan anyone be a father without beginning to be one? Yes, one who did not begin his existence. What begins to exist begins to be a father - God the Father did not begin at all. He is Father in the true sense, because He is not a son as well. Just as the Son is son in the true sense, because He is not a father as well. In our case, the word 'father' cannot be truly appropriate, because we must be fathers and sons.
Gregory of Nazianzus...a disposition is an unsatisfactory thing unless we give it practical effect - deeds show dispositions.
Gregory of Nazianzus...though every thinking being longs for God, the First Cause, it is powerless... to grasp Him. Tired with the yearning it chafes at the bit and, careless of the cost, it tries a second tack. Either it looks at things visible and makes of these a god - a gross mistake, for what visible thing is more sublime, more godlike, than its observer... - or else it discovers God through the beauty and order of things seen, using sight as a guide to what transcends sight without losing God through the grandeur of what it sees.
